Additionally UniTerm provides the XModem and Kermit file transfer protocols. The program and its documentation can be copied, distributed and used free of cost, but may not be sold for commercial purposes. Please contact me, if you find bugs or have suggestions for revised versions of UniTerm, but read appendix A and the implementation notes first. Some compromises have been made in the implementation of the VT100 132 column mode and double width characters will not work on a color monitor. Enhancements which are planned for future releases: -Tektronix 4105 commands (already started!) -sideways scrolling for 132 columns -cursor in 132 column mode -backwards scrolling -make UniTerm work with the blitter-chip -speedup the redrawing of vectors -enhanced color version (colors for highlighted etc.) GEM is a trademark of Digital Research Co. DEC,VT are trademarks of Digital Equipment Co. Tektronix is a trademark of Tektronix Co. Atari is a trademark of Atari Co. The Kermit file transfer protocol was developed by Frank da Cruz and Bill Catchings at Columbia University. Many thanks! This program was developed with ST Pascal Plus from CCD. Chapter - 2 Starting using UniTerm Requirements To use UniTerm you need: a ATARI ST computer a monochrome or color monitor a RS232 standard cable a computer/modem to connect to a floppy disk with UniTerm.PRG and UniTerm.RSC on it Getting started After connecting your ST to your host computer, double click the UniTerm Icon. After the program has been loaded you will (hopefully) see the UniTerm opening dialog. Now you can select the size of the vector/filecapture buffer, if you select 0 or a size to big for your free RAM no buffer will be allocated. If you are using UniTerm for the first time a alert box will appear, press (in this manual means the the key with xx on it) and ignore the warning message(UniTerm didn't find the file UNITERM.SET, which we will create later on), the screen will clear to white (on a monochrome monitor) with a status line on line 25. Press and the UniTerm help screen and a menu bar with following contents will appear: ------------------------------------------------- | Desk File Transfer Settings Other | ------------------------------------------------- Desk is the well known menu where you can start desk accessories. File allows you to select from: Load Setup load a previously saved setup from disk, Save Setup save the current settings of UniTerm to disk, Delete File delete a file, Set Path change the TOS current drive and path, Show Space show total available and free space on the current drive, Quit Menu leave this screen and return to terminal mode. Transfer selects the file transfer protocol you want to use: ASCII, XModem, YModem or Kermit. A change here is reflected in a different dialog box appearing when you select the File Transfer item in the Settings menu. Settings allows you to select from: RS232 sets the parameters of the serial port, Terminal sets the value of some terminal (VT100/102) parameters, Graphics sets the values for the graphics terminal module of UniTerm, File Transfer allows you to set the parameters for the current file transfer mode, Other has only one item right now: Edit Function Keys allows you to assign a string and/or macro commands to a function key. Select the RS232 item in the Settings menu and a new dialog will appear. Selecting the different values for the parameters is quite straightforward, just click on the buttons with the right values (we hope you know them, otherwise you will just have to experiment) and when you are finished select OK. To save the setup, select Save setup from the File menu, a normal GEM file selector dialog will appear, if you want to use this setup as default, save it with the name 'UNITERM.SET' and UniTerm will load it automatically on startup. To leave the help screen select Quit Menu or press the left mouse button once. If you have adjusted the parameters correctly, you should now be able to communicate with your host computer. Some operating systems (VMS) try to identify the terminal automatically, depending on your setup UniTerm will identify itself as a DEC VT200, VT102, VT100 or as an VT100 emulating a VT52. A VT102/VT200 has more 'advanced' editing functions (which results in less overhead in transmitting inserts etc.) so leave this option on VT102/VT200 if possible. If you have to enter the terminal type manually try VT102 first (changing from VT102 to VT100 or to VT200 only changes the report from UniTerm, not the actual commands UniTerm understands). Exiting UniTerm To stop UniTerm press , if there is nothing in the buffer you will be returned straightaway to the Desktop, otherwise an alertbox will appear asking for confirmation. Vector graphics mode After receiving the control code 'GS' (this can be turned off) or the 4105 command 'ESC'%!0 (ASCII control characters are enclosed in apostrophes to distinguish them from printable characters, a space is written 'SP') from the host, UniTerm switches to a separate graphics screen, if the host doesn't send 'ESC''FF' (the ASCII characters Escape and Formfeed) before starting a new picture, you will have to clear the screen manually with . The incoming characters will be interpreted as Tektronix encoded vectors or commands (see appendix A) until UniTerm receives one of the following codes: 'CAN' will return you to VT102 mode, 'ESC''FF' will clear the screen and enter Tektronix alpha mode. 'ESC'%!1 will return to VT102 mode. To return manually from Tektronix to VT200/VT102/VT100/VT52 mode press or select the appropriate mode from the item Terminal in the menu Settings. To view your picture again press (this just switches the physical screen (not the mode!). Be careful, selecting Tektronix 4010 mode manually will also reset the vector buffer! Zoom mode If you selected a vector buffer larger than zero kilo bytes, you can redraw a picture with different scaling factors. To select this mode press , the screen will be cleared, the current contents of the buffer will be drawn on the screen and the normal arrow mouse cursor will appear. To select the region of the picture you want to magnify, move the arrow to the upper left corner of the region, press the left mouse button and drag the mouse to the lower right corner of the region (a 'rubber box' should follow the arrow) and release the button. The resulting picture will be scaled so that the larger side of box will fit on the screen (if the option True Aspect is selected). You can repeat this operation until a magnificat ion factor of thirty is reached. will restore the previous scaling factors, the arrow keys will move the screen a 10th of the screen width/height in their direction and will leave zoom mode (all other keys only redraw the screen). Remember that if your picture is built out a lot of vectors, the redrawing may take some time! GIN mode The sequence 'ESC''SUB' will enter GIN mode from any of the Tektronix modes, it will not work from the VT102/VT100 mode since 'SUB' cancels any ANSI command. A crosshair cursor will appear which can be moved with the mouse. Pressing any key on the keyboard will cause a GIN report to be sent to the host and exits the GIN mode to Tektronix alpha mode. Tektronix 4014 alpha mode This mode is only included for compatibility with the GIN-mode and is not very useful. It is the same as 4010 alpha mode with one margin. This mode will probably be replaced in future versions with a 4105 compatible alphamode. Using the special keys Here is a list of the functions on the special keys (press and the key listed here): Erases the graphics screen from any terminal mode. Toggles the foreground/background color (white on black or black on white). Toggles between blinking and static cursor. Prints the contents of the textbuffer. Switches to the graphics screen and sets the terminal to Tektronix 4010 mode. Switches the screen and the terminal to VT102/VT100 mode. Resets the terminal, reads the default values from disk. Toggle autoprint. Enter zoommode. Reset the Tektronix mode. Send a short break (0.233 s) (doesn't drop DTR). Send a long break (3.5 s) (drops DTR). Send the answerback string Switch to 132 column mode (really only 128*24). Switch to 80 column mode. Start/stop file capture. Replay a captured file. Start file transfer. Atari screen dump.

Appendix - E The KeyEdit Program If you have got a complete release of UniTerm (V1.4 or later), you should have a copy of KeyEdit.Prg (Please check that it is for version 1.6f or higher!). This program enables you to edit the keyboard table stored in an UniTerm setup file, additionally you can create an executable keyboard table loader or just output the table itsself. Editing a UniTerm setup file Start KeyEdit.Prg and press when you see the opening dialog box. It will take a few seconds to create the display. You can only edit a existing setup file with predictable results, so select Load UniTerm File and select the file you want to edit. Select the key you want to change (select the approbiate part of the table (normal, shifted or caps locked)) and then the character you want to assign to the key. When you are finshed with editing, select Save UniTerm File. Don't try to change the characters on the keypad, cursorkeys or function-keys in the UniTerm setup file. These keys are hardwired via keycode to specific strings (like on a real VT100).

Screen dump to disk in DEGAS (tm) format. <.> Toggle 24/49 lines mode (only on monochrome monitor). Hold Screen ( on the german keyboard). Start the single-line editor. Chapter - 3 More about UniTerm Please read the chapter about the different file transfer protocols, for more information on them. RS232 Port Parameters To change these settings, press and select RS232 from the Settings menu. Following parameters can be changed: Baud selects the rate for the serial port. Flowcontrol selects the flowcontrol mode, these functions are implemented by the BIOS. Parity selects the parity mode, these modes are implemented by the BIOS. Data/Stop allows you to select the number of data and stop bits, implemented by the BIOS. Mode allows you to put the terminal in one of following modes: Full: Data typed on the terminal is echoed by the host computer. Echo: UniTerm echos user input on the screen. Local: User input is only sent to the screen. Terminal Parameters To change these settings, press and select Terminal from the Settings menu following parameters can be changed: Answerback is the string which is sent as answerback message. Terminal selects the terminal mode and change the terminal identification. 4014 selects 4014 alpha mode! Send/Receive masks out the 8th bit of sent or received bytes for the terminal emulations, set to 8 bits if you want to use the 8 bit VT2XX mode (this only effects ASCII file transfer and not the other file transfer modes). Attributes allows you to change the processing of text attributes: Ignore: All attributes except inverse are ignored, the terminal identifies itself as if it had the advanced video option (AVO), this is the quickest output mode. AVO: The terminal processes all DEC text attribute codes, slowest mode. NoAVO: The terminal only processes underline and inverse attributes. Scroll selects between slow and quick scroll. Print terminator determines if a 'FF' is sent after each print operation or not. Printer determines if a printer is connected or not. Newline Mode sets the VT100/102/200 newline mode. Cursor selects blinking or non blinking cursor. Tektronix mode enables or disables automatic switching to the Tektronix mode on receipt of a 'GS' character, useful on noisy telephone lines. Graphics Terminal Parameters Select Graphics from the Settings menu to change the parameters of the graphic terminal module: GIN Termination Sequence sets the string sent after a GIN report. Status Termination Sequence sets the string sent after a status report. Aspect this option controls the scaling of pictures. Ignore Deletes allows you to set processing of 'DEL' in the 4010 module. Setup Files All user setable parameters are stored in the setup files (including the function key strings etc.). Loading a setup file from a different version of UniTerm may result in a version conflict error message, if this happens UniTerm uses its internal defaults. File Capture/Playback The file capture routine uses a character translation table, which can be edited by selecting ASCII from the Transfer menu and then selecting File Transfer from the Settings menu. While file capture is in progress all screen output is translated too, so you will get a direct impression of what you are saving. The Playback function allows you to simulate input from the serial port, pressing allows you to abort, any other key will cause UniTerm to wait for another keypress. Editing Function Keys To edit the string assigned to a function key, press and select Edit Function Keys from the Other menu. You can edit the strings now, the cursor keys will move you to the string you want to edit, will clear the string, will delete to the left, the current character. Control codes can be entered by pressing and the appropriate key (see appendix B). The Statusline The 25th line on the screen is used as a statusline in text terminal mode, it should look like this: UniTerm V1.7a Full DBLCR 1234 ^ ^ ^ ^^^^^ ^^^^ | | | ||||| |||| | | Communication ||||| |||LED 4 | | Mode (Full,Echo,Local) ||||| ||LED 3 | Version ||||| |LED 2 | Identification ||||| LED 1 Program ||||Replace or Identification ||||Insert Mode |||File Capture on ||Keyboard Locked |Break DCD on The Single-Line Editor To make working on systems that don't have a single-line editor (short sle) easier, a simple sle is implemented in UniTerm. The last 20 lines typed by the user are stored in a circular buffer. Pressing starts the sle, the status line will clear and the current line will be displayed instead. Following functions are provided: Left and right cursor keys: move the cursor one character left or right. Up and down cursor keys: display the next or last line in the buffer. : delete the character under the cursor. : delete the character to the left of the cursor. : abort the sle. : send the line and leave the sle. The sle is always in insert mode. DON'T FORGET TO ERASE YOUR PASSWORDS! Chapter - 4 File Transfer General To change the current file transfer mode use the Transfer menu. Changing the file transfer type here, changes the dialog box that is displayed when you select File Transfer from the Settings menu and what happens when you type (start file transfer). ASCII file transfer Using ASCII file transfer There is nothing much to say about ASCII file transfer, just press and choose the file you want to send. Pressing gets you to the Help screen, so you can change the delay between characters to a different value during an upload (this is useful with VMS which normally has a lot of trouble with the first line sent). The transfer can be inter rupted at any time by pressing . Normally some experimentation is needed to find the shortest delay time for your system. You can use a character translation table to map incoming characters to Atari characters. To receive files use the file capture function. A translation table is used in the same way as with sending files. When file capture is in effect the characters are displayed as they will be saved. Setting the ASCII file transfer parameters The following parameters can be set: Start of file transfer a string that is sent before file transfer starts. End of file transfer a string that is sent when the transfer finishes. Send determines if the output translation table is used for sending files. Receive determines if the input translation table is used for capturing files. Delay after every character sets the time [ms] UniTerm waits after every character sent (this is implemented with the 200Hz system clock=>resolution is 5 ms). Method if Paced by Echo is selected, UniTerm waits for every character sent to be echoed (except ASCII control codes), this doesn't time out! Send EOL as selects if 'CR''LF' is sent as 'CR''LF','CR','LF' or 'SP''CR'. This function will send single 'CR''s and 'LF''s correctly! Translation on input and Translation on output enables you to edit the translation tables, enter the decimal ASCII values of the characters or nothing if you want the character to be ignored. XModem/YModem Using XModem To receive a file start the remote XModem and type . To receive a file select Receive from the dialog box and enter the filename in the file selector form. If you have set the error check mode to CRC UniTerm will try to initiate a file transfer with CRC, if it gets no response in the maximum allowed number of errors, it will retry with the normal checksum. To send a file select Send and enter the name of the file in the file selector. Using YModem batch This implementation of YModem is probably not quite conform with the actual YModem protocol as it was impossible to get a proper protocol definition for the current release of UniTerm. What it does is: send/receive a header packet with filename and size before starting a XModem file transfer. The file date and time is set to 0 and the attributes to 000644 (octal) on sending and ignored on receiving. Filename collision handling and wildcard expansion are done on receiving/sending a group of files. Setting the XModem parameters The following parameters can be set: Timeout after sets the maximum time XModem waits for a character to be received from the serial port. Maximum number of errors sets the maximum number of errors before the file transfer is aborted. Accept ASCII NUL allows you to use XModem for none binary file transfers, when ASCII 'NUL' is used as padding character. Packet size chooses the packet size for XModem transfers, the 1kB size may be more efficient on noise free lines. Error check type sets the default checksum type, if possible use the CRC check for the larger packet size. Kermit UniTerm Kermit capabilities UniTerm Kermit capabilities at a glance: Local operation: Yes Remote operation: No Transfers text files: Yes Transfers binary files: Yes Wildcard send: Yes ^X/^Y interuption: Yes Filename collision avoidance: Yes Can time out: Yes 8th-bit prefixing: Yes Repeat count prefixing: No Alternate block checks: No Terminal emulation: Yes (UniTerm) Communication settings: Yes (UniTerm) Transmit BREAK: Yes (UniTerm) IBM mainframe communications: Yes (not tested) Transaction logging: No Session logging: No Act as server: No Talk to server: Yes Advanced server functions: No Advanced commands for servers: Yes Local file mangement: Yes Handle file attributes: No Command/init files: No Command macros: No Large packets: No Windows: No Please don't forget if you miss some feature, that UniTerm is a terminal emulator and not a 'real' Kermit. Simple file transfer Check that the host kermit and UniTerm have the same parity set. To receive a file type the correct command for the remote Kermit and type on the ST keyboard, a large dialog box should appear. Select Receive if you want to use a different name than the original filename use the file selector form to select a name (this will only effect the first file received in a mutiple file transfer). If you want to receive the files with the names supplied by the host, just press (if you enter a path in this situation, the current TOS drive and path is set to the value you entered). A new form will appear and will display the current file being received, the total number of packets, the current number of errors and timeouts and the last non-fatal error that occured. The transfer can be aborted by typing . To send a single file or a group of files, setup the remote host for receiving, type and select Send. Enter the filename or wildcards (*, ?) in the file selector dialog and press . Binary file transfer Set both sides (host and local computer) to binary mode (on most mainframes with 'set file type binary' or 'set file binary', select the |Binary| button on UniTerm ), if you have set parity to none and have selected 8 data bits, binary files will be transferred without 8th bit prefixing in all other cases 8th bit prefixing will be used. One note, since the Kermit 'end of record' is the same as the TOS 'end of line' no translation of 'CR''s or 'LF''s is done, this may lead to problems if you have a file on the ST which uses 'LF' as 'end of line' marker. Server commands This is probably the simplest way to use Kermit, connect to the remote host and start the remote Kermit in server mode. A large subset of the possible Kermit server commands is implemented (not implemented: Journal, Who, Variable): Put send a file to the host. Get receive a file from the host. Finish terminate the remote Kermit. Logout terminate the remote Kermit and logout. Dir send a directory to the local Kermit and have it displayed on the screen (argument: file-spec). Remote send a command to the remote host (argument: command line). Type send a file to the local Kermit and display it on the screen (argument: file). CWD change the current working directory of the remote Kermit (arguments: directory, password). Usage show disk usage (argument: area). Program start a program on the host computer (arguments: program-file, program-commands). Erase delete a file on the host computer (argument: file). Copy copy a file on the host computer (arguments: source, destination). Rename rename a file on the host computer (arguments: oldname, newname). Login login on a remote Kermit in server mode (arguments: user, password, account). Help get help from the remote host (argument: topic). Status get the current status of the server. For more information consult the 'Kermit Protocol Manual'. Setting the Kermit parameters The following parameters can be set: Timeout after sets the maximum time Kermit waits for a character to be received from the serial port. Maximum number of retrys the maximum number of retrys before the transmission is aborted. Number of padding characters the number of padding characters sent before each packet. Packet size the maimum packet size you want to use (maximum size without large packets is 94. Quote character the ASCII character used for control character quoting. 8 bit quote character the ASCII character used for 8th bit quoting. Repeat prefix character the character used for repeat prefixing (not implemented!). Padding character the character used for padding. Start of packet the character that marks the start of a Kermit packet. IBM mode wait for a 'XOn' character before sending a packet (XOn/XOff flow control naturally has to be turned off for this to work). Error check type right now only the standard Kermit single character checksum. Normally you shouldn't have to change any of these parameters, please consult the Kermit literature for more details. Chapter - 5 Implementation Notes General Most of UniTerm is written in CCD/OSS Pascal and uses standard GEM,GEMDos,Bios and XBios calls. The exceptions are: Scrolling up, this is done with a assembler routine instead of a raster operations. Peeking and poking in user and supervisor status is done in assembler. Character output with text attributes set, is done with TXTBLT (which doesn't help very much speedwise) In future versions probably more will be done in assembler. The Bios input buffer for the serial port is expanded to 10000 bytes. If no attributes except reverse are set and the character cell height is 16 or 8 pixels, screen output is done with the Bios call BConout (Bios 3), this is at least twice as fast as using GEMDos and three and half times faster than using GEM. Typical times (may change from version to version, these were taken with Beta version 0.7): Polling of the serial port and keyboard (main loop): 0.65ms (Beta V1.2 0.48ms) (if there are characters in the input buffer, a maximum of 20 are processed before the keyboard is polled again) The following data was measured with simulated input to the VT102 command processing routine, the times are per operation: Carriage return 0.6ms Clear complete screen ('ESC'[2K): 140 ms Clear complete line ('ESC'[2J): 10.0ms Absolute cursor address combination ('ESC'[H'ESC'[10;10H): 5.6ms Linefeed with scroll: 30.0ms 40'000 characters 8 per line 4.4ms 80 per line 1.0ms (Beta V1.2 0.88ms) 4'000 characters bold (highlighted) 80 per line 3.5ms To decode one character without any output operation (moving of cursor etc.) takes less than 0.5 ms. Use of UniTerm at 9600 baud is probably not unresonable, but it may need flowcontrol. The carrier detect signal and the break bit on the Mfp are polled once per main loop and if they are present a appropriate message is displayed. VT102/VT100 Mode Smooth Scrolling Only works upwards (this is hopefully the only direction anybody really needs ), this will be fixed the day I get a blitter. 132 Column Mode Only 128 columns wide, this is due to the 640 pixel resolution of the ST in horizontal direction. No cursor is shown in this mode! Double Height/Width Characters Restrictions: no double width in color. Extended character set in 8 bit mode Using the GR character set will work, but is probably very slow due to the fact that the font has to set/reset for every character. VT200 Mode VT200 function keys There is no default assignment of the VT200 function keys to ST keys, except for the downloadable function key strings. If you need the default VT200 keys (-> appendix F), build yourself a setup file with the right settings. C0/C1 Modes Not implemented, that means UniTerm always sends C0 codes (7 bit), received C1 codes will be interpreted correctlly. International character set The international character set is the default GR set (->the characters that are between ASCII 128 and 256). For technical reasons use of the GR set is slow (the set is changed for every character!). Downloadable character set Not implemented (very resolution dependent, useless on the ST). Downloadable function keys The lock/unlock/erase parameters are ignored. The mapping of the keys is described in appendix F, maximum string length per key is 80 characters (DON'T FORGET THAT % IS A SPECIAL CHARACTER FOR UNITERM!). Regis Not implemented (very resolution dependent, useless on the ST). Tektronix Mode General The Tektronix mode is still a bit in a mess. This will change with the using the 4105 command set, this implies that you should only use the vector mode of the 4010 emulation as all other 4010 commands will probably be removed from the program. Right now scaling is done with respect to a 4010 with 1024*780 points, this probably will change for the 4105 (512*360) emulation. In Tek coordinates the screen measures 4096*3120 points (4105: 4096*3072 points). For redrawing and zooming purposes the incoming characters are stored in a linear buffer. This is quite a memory saving way to store them, but on the other hand this means they have to be decoded every time the vectors are drawn. Alpha Mode Restrictions: 1 margin, all (well nearly all) character sizes are the same only the spacing is different. Vector Mode Zoom Mode Restrictions: No zooming of graph text, slow. Problems Sometimes the serial port seems to blocked (this has happened to me with other ST terminal emulators as well), the reason for this still hasn't been discovered (probably due to a bug in the ST Bios). Don't use the Set RS232 Port Parameters dialog in an editor or the like, for some mysterious reason the serial port outputs a delete character if you actually change something and exit with OK (probably due to a bug in the ST Bios). Don't try to use the underscore character in the file-selector dialogs (this is a bug in GEM).
